Exchange 2010 SSL Certificate issue

[Deadmanza]

Hey All,

Having a bit of an issue renewing an SSL cert for one of my clients. Have done this the past few years and have had no issue, however for some reason am hitting a brick wall.

I need my cert to reflect as follows -

Issued to {Domain}.dyndns.org
Issued by {Domain}.dyndns.org

Have had this working before, however for the life of me I am unable to remember how to get the issued by name to be anything other than the name of the CA i am using to complete the certificate request.

I have it as follows at the moment

Issued to {Domain}.dyndns.org
Issued By CA

This works fine for OWA, if you install the OWA Cert and the CA cert, however it does not work so well with OA and mobile devices...

Any help will be much appreciated.
